We ship a Java based VNC client, and have encountered problems
with:
        - the Code Signing of the .JAR file had expired, and
so a local Java installation refused to run it, deeming it
insecure. Solution was to update what we shipped with a more
corrent copy
        - the Java on the local machine, which was being
started by the browser, was 'stale' and had been updated
upstream; Solution there was an update of that Java (This
especially seen on OS/X units)
        - the Code Signing key used to sign the .JAR was
counteresigned by a CA (Certificate Authority) not known to
the local Java installation.  Solution was to add that CA's
'chain of trust' into the local ancillary install for the
local Java install

Reading the messages closely is needed, to understand what is
in play
